As tech companies like Facebook Inc. and Google vacuum up billions of dollars in online advertising, they’re pouring their own marketing dollars into billboards and other forms of outdoor signage. That’s driving growth in one of the oldest forms of marketing and is one reason why the category is the only traditional channel expected to grow this year.

Coca-Cola is no stranger to outdoor advertising, making their first appearance in Times Square over a century ago. They recently unveiled this monster of an LED sign, which is not only impressive, but the first of its kind!

Out of home (OOH) advertising is the most effective offline medium in driving online activity, according to a new study released by Nielsen. The study found OOH delivers more online activity per ad dollar spent compared to television, radio, and print.
